| 摘要 |
An inorganic phosphorescent article having a formed phosphorescent layer where the phosphorescent layer is not mixed with a frit and the majority of the layer comprises photoluminescent phosphors comprising rare earth doped alkaline earth aluminates, rare earth doped alkaline earth silicates, zinc sulfide doped with copper or mixtures thereof. The phosphorescent articles of the present invention may be formed as tile bodies and fired at high temperatures between 1000C and 1600C providing durable ceramic and porcelain tiles suitable for use in emergency lighting flooring systems, aqueous environments such as pools and spas, and outdoor pathway lighting. |
